About Mary Cowan
Mary A. Cowan, known as The Borgia of Maine, was an American serial killer who poisoned two husbands and four children between 1884 and 1894, and attempted to murder a third husband. Convicted of killing her step-son Willis Cowan in September 1894, Cowan was sentenced to life imprisonment and sent off to the Maine State Prison, where she died a few years later from an unspecified illness.
